Subject: [PATCH] Do not add -llasem and -lmtex2MML to $LIBS when pkg_config is used
|
|
|
|
pkg-config provides correct arguments to the linker.
|
|
|
|
It seems that the lasem library is named differently on various
|
|
systems. Unmodified lasem 0.5.0 installs library named
|
|
liblasm-0.6.so.5.0.0 (and symlink liblasm.so), so linker fails when
|
|
-llasm is passed.
|
|
